硼酸，Boric acid；BioReagent, for molecular biology, suitable for cell culture, suitable for plant cell culture, ≥99.5%

Boric acid is a weak monobasic Lewis acid (electron pair acceptor), which reacts reversibly with alcohols. It is used in dermal and women′s hygiene products due to its mild antibacterial and antifungal effects. Boric acid is used as a buffer in ophthalmic products. It acts as an effective solid lubrication agent because of its molecular structure. Boric acid finds its applications in glass making, fire retardant, and fertilizer. Boric acid is used in biochemistry in buffer solutions. It also forms complex equilibria in solution, with the tetraborate ion (B4O7 2- ) being the predominant species. Borate buffers are involved in discontinuous electrophoresis and capillary electrophoresis systems for the separation of proteins and nucleic acids.
